Abstract

Muscle is a contractile tissue responsible for maintaining posture and the movement of all parts of the body. Prolonged oxidizative stress can lead to the damage of cells, tissues, and organs. In this study, we investigated the possibility of oxidative stress in the process of myoblast differentiation of C2C12 cells. First, the myoblast differentiation model of C2C12 cells was constructed and verified by Giemsa staining. The expression of hypoxia inducible factor1-alpha (HIF1-α), hypoxia inducible factor1-beta (HIF1-β), Von Hippel-Lindau (VHL), lysyl oxidase (Lox), EGL-9 family hypoxia-inducible factor 1 (EGLN1), proline 4-hydroxylase alpha 1 (P4HA1) and heme oxygenase-1 (HOMX1) in the process of myoblast differentiation was verified by in vitro experiments and Gene Expression Omnibus (GEO) bioinformatic analysis. We found that with the increased expression of myogenic factor 5 (MYF5), myogenic differentiation 1 (MYOD1), and Desmin, myotube fusion became more obvious during the process of C2C12 cell differentiation. Both experimental and GEO analysis indicated that the expression of HIF1-α, HIF1-β, VHL, LOX, EGLN1 and P4HA1 increased, and the expression of HOMX1 decreased during myogenic differentiation. Therefore, we suggest that the myoblast differentiation of C2C12 cells may be related to oxidative stress. Their possible relationship was proposed, though further studies are needed.
